RICHARD A. BREUL AND CHARLES BREUL, OF BRIDGEPORT, CONN ECTICU'I;

SAID CHARLES BREUL ASSIGNO R TO SAID RICHARD A. BREUL.

CHAIN-LINK.

SPECIFICATION forming part of Letters Patent No. 530,921, dated December18, 1894.

Application filed June 12, 1894. Serial No. 514.307. (No model.)

To all whom it may concern.-

Be it known that we, RICHARD A.BREUL and CHARLES BREUL, citizens of theUnited States, residing at Bridgeport, in the county of Fairfield andState of Connecticut, have invented certain new and useful Improvementsin Chain-Links; and we do declare the following to be a full, clear, andexact description of the, invention, such as will enable others skilledin the art to which it appertains to make and use the same,referencebeing had to the accompanying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

(5 Our invention consists in a new and improved wire chain link, whichis largely designed as an improvement on the wire link for which PatentNo. 518,484 was granted to one of the present inventors on April 17,

1894; this invention embodying certain novel and valuable features whichadd materially to the strength and wearing qualities of, the link: andour invention will be hereinafter fully described and claimed.

2 5 Referring to the accompanying drawings:

Figure 1 is a perspective view of a piece of our improved chain. Fig. 2is a detail view, on an enlarged scale, of one of the links. Fig. 3 is asimilar view taken from the opposite side to that shown in Fig. 2. Fig.4 is an edge View. Figs. 5 and 6 are respectively a perspective view andan edge view showing the double loop of the link arranged in a plane atright angles to the single loop, as herein- 5 after described;

Our new and improved chain links are formed each of a single piece orlength of wire, which is bent at its center to form a single loop, 1,said loop being about half the 0 length of the proposed link; the sidewires, 2, at the inner end of this loop being offset or bent inwardtoward each other, at 3, 3, then offset again at 4 in the generaldirection of the link, crossing each other as shown, the 5 wire-ends orshanks being then curved to form loops 5, 5, which register with eachother, forming a double loop as shown in Figs. 1 to 4 in the same planewith the single loop 1; the ends of the wire running back to the centraloffsets where they are passed curves or bends, asvarious minor changesor deflections may be made without departing from the spirit of ourinvention.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

1. A chain link formed of a single piece of wire bent at its center toform the single loop, the side wires being then offset toward each otherat the termination of said loop, then offset in the general direction ofthe link, extended and crossing each other, and then curved to form thetwo registering loops, the ends of the wire running back and passingthrough the single loop, and terminating in eyes which closely encirclethe offsets of their respective shanks; substantially as set forth.

2. A chain link formed of a single piece of wire, bent at its center toform the single loop, the side wires being theuoffset toward each otherat the termination of said loop, then offset again in the generaldirection of the link, extending and crossing each other, and thencurved to form the two registering loops which extend in the same planewith the single loop forming the other half of the link, the ends of thewire running back past the central ofisets, passing through the singleloop, and terminating in the eyes which closely encircle the ofisets oftheir respective shanks; substantially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
